EXAMPLE 16 (R)-5-Methyl-6-[4-(4-oxo-1,4-dihydropyridin-1-yl)phenyl]-4,5-dihydro-3(2H)-pyridazinone A mixture of (R)-6-(4-aminophenyl)-5-methyl-4,5-dihydro-3(2H)-pyridazinone (100 mg), 4H-pyran-4-one (52 mg) and hydrochloric acid (0.1N, 1 ml) in water (1.3 ml) was stirred under reflux under nitrogen for 3 hours. Aqueous ammonia (880, 0.01 ml) was added to the cooled reaction mixture to afford the title compound which was collected, washed with water and dried, 91 mg, m.p. 257-8 C. (softens 120 C.), [alpha]D25 =-369.5 (1.07% in dimethylformamide)., 36725-28-7
The synthetic route of 36725-28-7 has been constantly updated, and we look forward to future research findings.
